How would I call a wildcard variable in python POST method? -

i still fresh python , trying web app return wildcard variable (as catch-all). here current code, functions correctly defined dictionary paths empty form responses, cant function undefined entries:

def post(self):     form = web.input(action=none)      if session.room:         if form.action:             session.room = session.room.go(form.action)         if not form.action:             web.seeother("/")         return render.show_room(room=session.room)      else:         web.seeother("/") 

here dictionary reference i'm attempting ('*' wildcard catch-all):

escape_pod.add_paths({     '2': the_end_winner,     '*': the_end_loser })  the_bridge.add_paths({     'throw bomb': bridge_death,     'slowly place bomb': escape_pod,     '*': the_bridge })  laser_weapon_armory.add_paths({     '132': the_bridge,     '*': laser_death })  central_corridor.add_paths({     'shoot!': shoot_death,     'dodge!': dodge_death,     'barrel roll': poor_sport,     'tell joke': laser_weapon_armory,     '*': central_corridor })  poor_sport.add_paths({     'let me try again': central_corridor,     '*': poor_sport })
